Specification forming purt of Letters Patent No. 150,342, dated 28, 1874; applicatiorled April 3, 1874.

Be it known that I, CHARLES MEYER, of

' the city, county, and State of New York, have invented a new andu'seful Improvement in dans and Jars; and I' do hereby declare the following to be a full, clear, and exact descrip- .twat-hereof, which will enable those skilled in L -the art tomake and use the same, reference being had to the accompanying drawing forming part of this specification, in whichdrawin g ment. cover. l Fig. 3 is a planview of the top of the can or jar made according to my invention,

the cover and packing-ring being removed.

Similar letters indicate corresponding parts. This inventionv relates .to cans and jars of metal,- glass, or other material; and consists in an improved method of fastening the covers thereto. The top of the can or jar is lprovided with an internal locking-ange, which is recessed at one ormore points to receive the locking-arms of the cover, and permit them to be brought under the divisions of the lockingof the can or jar is provided with a, seat near,

its outer edge to receive a packing-ring or gasket, and l prefer to make such seat of a ridge shape to t a corresponding groove in the cover. The coverconsists of a disk of a diameter equal toor a little greater than that ofthe top of the can or jar, and it is pro/vided with lugs or thumbpieces,which enable me .to tighten or loosen' the cover with the hand. Upon the under side of the cover are arranged locking-arms, which enterthe recesses in the locking-flange of the vessel, and which, by being turned under the locking-flange, draw the cover close to the can or jar, and produce a tight joint between them. 1

The letter A designates a tin can, which is open at top, except that it has an`inner horizontal flange, B, which forms, with the can, a

locking device to fasten the cover andcan to each other. The flange B consists of a plate Figure lis a vertical section of my improve- Flg. 2 is an inverted plan view of the l to the edge of the can; but the plate, before it is applied to the can, is cut out by a die-cutter to the shape. shown in the drawing, or tof `Whateverr shape is required to conforml to and admit the locking-arms ofthe cover, and it is,' when being out, pressed by the die in such a manner as to turn over its outer edge C, and produce a ridge, D, on its topsurface, to form a seat for the cover, and for the packing-ring 0. In the example here shown, the flange B .is made with six projections, E, separated from each other by recesses F, to correspond to the locking-arms of the cover; but it is evident that a less number can be use-d with good et'- screw-thread, and their under side is provided with a ridge, Gr, which increases in thickness in the direction toward which the locking-arms of the cover are to be turned, so that the arms are tightened as 'they are turned against the ridges. The inclined positions of the projecting parts E of the locking-flange, and they ridges G thereon, can be produced by the ac-` tion ofthe dies when the Iiange is being cut, but, if desired, the ridges can be produced by solder or other methods. The cover H consists, in this example, of a dat metallic plate, provided with four lugs, I, projecting, at equal distances apart, from its edge, so as to form thumb-pieces for turning the cover upon the can by hand. The lugs I may be less in number, or, instead of them,Iv lugs or depressions may befformed on the top of the cover to rcceive a wrench for turning the cover. From the under side of .the cover project lockingarms J, which are bent to correspond to the inclined positions on the lockin g-iiange of the can. In this example, thesearms are formed on the edge ot' aplate, K, which is riveted to the under side of the cover. The under side of the cover, Anear its edge, is provided with a groove, L, arranged so as to receive the ridgeseat D'of the can, and help make a tight joint.

The ridge D and the groove in the cover serve also as a guide to the cover in adjusting it on the can.

My invention is applicable to glass jars, as well as to metallic cans, and the vessels to which my invention is applied can be used for holding paints, as Well. as fruit and other articl'cs, which it maybe desired to keep air-tight.

NVhat I clainlas new, and desire to secure b v Letters Patent, is-

1. A can or jar provided with surrounding ridge-seat D and a horizontal ange, B, having projections E, extending inwardly over` a portion of the mouth of the can or jar, in combination with a cover, the locking-arms J of which pass under the projections E, substantially as described, for the purpose specified.

the projections E, ridge-seat D, and inclined p ridges Gr with .the cover H and its lockingarms J, substantially as described.
